*New:*

    - Add support for Python3
    - Clean up documentation
    - Document extension points
    - Add support for ``get_or_create`` in :class:`~factory.DjangoModelFactory`

*Deprecation:*

    - Remove STRATEGY_*
    - Remove :meth:`~factory.Factory.set_building_function` / :meth:`~factory.Factory.set_creation_function`


1.3.0 (2013-03-11)
------------------

.. warning:: This version deprecates many magic or unexplicit features that will be
             removed in v2.0.0.

             Please read the :ref:`changelog-1-3-0-upgrading` section, then run your
             tests with ``python -W default`` to see all remaining warnings.

New
"""

- **Global:**
    - Rewrite the whole documentation
    - Provide a dedicated :class:`~factory.MogoFactory` subclass of :class:`~factory.Factory`

- **The Factory class:**
    - Better creation/building customization hooks at :meth:`factory.Factory._build` and :meth:`factory.Factory.create`
    - Add support for passing non-kwarg parameters to a :class:`~factory.Factory`
      wrapped class through :attr:`~factory.Factory.FACTORY_ARG_PARAMETERS`.
    - Keep the :attr:`~factory.Factory.FACTORY_FOR` attribute in :class:`~factory.Factory` classes

- **Declarations:**
    - Allow :class:`~factory.SubFactory` to solve circular dependencies between factories
    - Enhance :class:`~factory.SelfAttribute` to handle "container" attribute fetching
    - Add a :attr:`~factory.Iterator.getter` to :class:`~factory.Iterator`
      declarations
    - A :class:`~factory.Iterator` may be prevented from cycling by setting
      its :attr:`~factory.Iterator.cycle` argument to ``False``
    - Allow overriding default arguments in a :class:`~factory.PostGenerationMethodCall`
      when generating an instance of the factory
    - An object created by a :class:`~factory.DjangoModelFactory` will be saved
      again after :class:`~factory.PostGeneration` hooks execution


Pending deprecation
"""""""""""""""""""

The following features have been deprecated and will be removed in an upcoming release.

- **Declarations:**
    - :class:`~factory.InfiniteIterator` is deprecated in favor of :class:`~factory.Iterator`
    - :class:`~factory.CircularSubFactory` is deprecated in favor of :class:`~factory.SubFactory`
    - The ``extract_prefix`` argument to :meth:`~factory.post_generation` is now deprecated

- **Factory:**
    - Usage of :meth:`~factory.Factory.set_creation_function` and :meth:`~factory.Factory.set_building_function`
      are now deprecated
    - Implicit associated class discovery is no longer supported, you must set the :attr:`~factory.Factory.FACTORY_FOR`
      attribute on all :class:`~factory.Factory` subclasses


.. _changelog-1-3-0-upgrading:

Upgrading
"""""""""

This version deprecates a few magic or undocumented features.
All warnings will turn into errors starting from v2.0.0.

In order to upgrade client code, apply the following rules:

- Add a ``FACTORY_FOR`` attribute pointing to the target class to each
  :class:`~factory.Factory`, instead of relying on automagic associated class
  discovery
- When using factory_boy for Django models, have each factory inherit from
  :class:`~factory.DjangoModelFactory`
- Replace ``factory.CircularSubFactory('some.module', 'Symbol')`` with
  ``factory.SubFactory('some.module.Symbol')``
- Replace ``factory.InfiniteIterator(iterable)`` with ``factory.Iterator(iterable)``
- Replace ``@factory.post_generation()`` with ``@factory.post_generation``
- Replace ``factory.set_building_function(SomeFactory, building_function)`` with
  an override of the :meth:`~factory.Factory._build` method of ``SomeFactory``
- Replace ``factory.set_creation_function(SomeFactory, creation_function)`` with
  an override of the :meth:`~factory.Factory._create` method of ``SomeFactory``
